| Research Abstract |
Lymphoma cells proliferate predominantly in lymph node. Metastatic potential of lymphoma cells contributes to determine prognosis of lymphoma patients. The molecular mechanisms underlying metastatic potentialof lymphoma cells has not yet been fully elucidated. Cell migration plays a key role in metastatic potential in lymphoma cells. In this study, we have focused integrin associated proteins (IAP)/CD47 in B cell malignancies, and have demonstrated that following results,
1) Anti-CD47 monoclonal antibody, B6H12, produced signals to promote polarization with lamellipodia in B cell lines.
2) B6H12 acivate migratory activity of BALL cells to fibronectin.
3) Dominant negative form of CDC42 completely blocked B6h12 induced morphologic and functional changes.
